Paper on Hybrid Operated Cascade Thrust Reversal

Abstract

Through this paper an attempt is made to focus on a special technology based on application of cascade thrust reverser in turbofan engine which is common to the aviation industries but an uncommon in general. The airlines accept that cascade thrust reverser is necessary for safe operations because it provides an added margin of safety for transport aircraft operations. In this technology, forward thrust produced by turbofan engine of aircraft is diverged to reverse direction so as to provide an additional deceleration effect during landing and power back effect. Technical aspects such as engine power reverse thrust characteristics, modes of operation and speed limits of thrust reverser mechanism along with technical problems are discussed. As this mechanism is crucial for safety of aircraft therefore thrust reverser & engine maintenance-schedule is also discussed further. Basically here we introduce modified version prototype for cascade shell type thrust reversal incorporated with guide vane to deflect air in forward direction. Here we are implementing hybrid functioning of thrust reversal in addition with Automatic plus manual application by using micro-controller. Micro-controller basically programmed to sense speed of air or speed of aircraft during landing (applicable to operate thrust reversal) and this passes signal to linear actuator connected to thrust reversal and allow thrust reversal duct to open the vane and deflect the air flow in forward direction.
